The Bald Eagle's Lifespan

The Bald Eagle's Lifespan

Being the national bird of America, the eagle has become the global symbol of freedom and bravery. It can be easily identified in photos as an eagle with a white head and a golden beak. But being a bird of prey that eats other animals for food, not many people name it as their favorite bird. A lot of information about this bird is not very known to the public; details like actual diet, habitat, and the lifespan.

The Eagle's Diet

All animals, including bald eagle, live in habitats in which there is a rich source of food. Even though it is a predatory bird, the common misconception is that it eats roosters and little mammals,although it actually eats carrion (dead or dying fish); particularly salmon. The eagle is more of a scavenger than a real predator. They are rarely observed to prey on hen and other livestock, but they do take advantage of the most available food source around them.

The North American Bald Eagle

The bald eagle is the only bird which is recognized to be uniquely found in North America. Their boundaries stretch from down south to Mexico and way up north to Alaska and Canada. Their natural habitats are near their food sources; near waters rich with salmon, making the western half of North America it's ideal home.

The Bald Eagle Lifespan

All living creatures' lifespan depends on lots of elements; their diet, habitat, food source, their place in the food chain etc. Bald eagles can live up to the age of forty, but most eagles living in the wild have a lifespan averaging between fifteen to twenty years. The oldest identified of this species lived up to the age of forty-eight. In the past, their lifespan was much shorter due to hunting. However, since hunting them is prohibited and considered a serious crime, bald eagles can now live up to their full age potential.

The Hoax About The Eagle's Rebirth

Some stories tell the rebirth of the eagle, allowing it to live for yet another thirty years making the eagle the longest living bird. The story talks about a time in an eagle's life when the eagle will lose its beak, talons and feathers providing way for new ones to grow; thus it is reborn to live an additional life. Although this story revolved around the internet raising questions from bald eagle lovers about the reality in it, professionals announced that the story is an absolute hoax. Professionals say that the story lacks scientific and logical proof on the possibility of the eagle's survival without its beaks. It could have died of starvation way before the new beak could have sprouted. The story is no more than an allegory about life starting at the age of forty and moving on as authorities suggests, and not to be taken seriously.

The Symbol

According to experts, parrots and other birds can live longer than the bald eagle. It is not the longest living bird around, unlike the tale of its rebirth suggests. This bird may not be the all time crowd favorite; however, it will remain as the trademark of the USA and a symbol of freedom and bravery.
